Can a man have a vasectomy reversal after it has been done 25 years ago?

Yes, it is possible to reverse a vasectomy. Usually if you're not sure this is what you want permanently, they can surgically insert valves instead of just cutting and tying

off or cauterizing the tubes and this makes it quiet easy to reverse a vasectomy. How ever it's a bit more costly to do that.

They can also be reversed with micro surgery to reattach the tubes together also a

bit spendy.

Hope this helps.
